Give them a call they are very nice people and will answer all your questions. I have tried other finishes in the past but this was by far the best for my needs. I don't want to debate the pros or cons of finish, you have to just try them and use what works best for you. I use an HVLP sprayer.
One of the things I like best with Enduro is the way the finish looks. Many Water born finishes although good, have a bluish look to them and can't be used over dark woods like Ebony. This finish has incredible optical clarity. The colors in the wood and inlayed look almost iridescent. Many finishes, even some of the most popular used by many cue makers I have seen at the shows, leave the cue looking like it has a plastic coating on it or something, you can't appreciate the beauty of the wood.
These people were at the BCA show a few years ago by the way and had a lot of guys talking with them. I would not be surprised if there are a few cue makers out there using their products but not telling anyone. Like I said in my other post there is sort of a stigma with the water born finishes or they may just be secretive. I think with so many repair and part time cue makers working in their houses the safety factor would be very appealing.
That's just a bonus though, it is a great finish, I can't think of any minuses, it meets, at least for me, all the needs I have for finishing cues. It's another choice to think about. I also use it with the cross linker.
